Included is also a bit of rework of the SOR driver in preparation to add DisplayPort support as well as some refactoring and cleanup. Finally, all output drivers are converted to runtime PM, which greatly simplifies the handling of clocks and resets. * tag 'drm/tegra/for-4.8-rc1' of git://anongit.freedesktop.org/tegra/linux: (35 commits) drm/tegra: sor: Reject HDMI 2.0 modes drm/tegra: sor: Prepare for generic PM domain support drm/tegra: dsi: Prepare for generic PM domain support drm/tegra: sor: Make XBAR configurable per SoC drm/tegra: sor: Use sor1_src clock to set parent for HDMI dt-bindings: display: tegra: Add source clock for SOR drm/tegra: sor: Implement sor1_brick clock drm/tegra: sor: Implement runtime PM drm/tegra: hdmi: Implement runtime PM drm/tegra: dsi: Implement runtime PM drm/tegra: dc: Implement runtime PM drm/tegra: hdmi: Enable audio over HDMI drm/tegra: sor: Do not support deep color modes drm/tegra: sor: Extract tegra_sor_mode_set() drm/tegra: sor: Split out tegra_sor_apply_config() drm/tegra: sor: Rename tegra_sor_calc_config() drm/tegra: sor: Factor out tegra_sor_set_parent_clock() drm/tegra: dpaux: Add pinctrl support dt-bindings: Add bindings for Tegra DPAUX pinctrl driver drm/tegra: Prepare DPAUX for supporting generic PM domains ... 2016-07-04T09:34:31+00:00 Thierry Reding treding@nvidia.com 2015-01-15T12:43:18+00:00 urn:sha1:2ccb396e9dd4536cfb7e8c4fd892d215c7aec2b6 In order to use the HDA codec to forward audio data to the HDMI codec it needs the ELD that is parsed from the monitor's EDID. Also implement an interoperability mechanism between the HDA controller and the HDMI codec. This uses vendor-defined scratch registers to pass data from the HDMI codec driver to the HDMI driver (that implements the receiving end of the HDMI codec). A custom format is used to pass audio sample rate and channel count to the HDMI driver.

Hook up the CRTCs, planes' and connectors' ->atomic_destroy_state() callback to ensure that the atomic state objects don't leak. Furthermore the CRTC now implements the ->mode_set_nofb() callback that is used by new helpers to implement ->mode_set() and ->mode_set_base(). These new helpers also make use of the new plane helper functions which the driver now provides.
